Château de Benauge is a medieval fortress located in the Entre-deux-mers region between Cadillac and Targon, notable for its strategic elevated position overlooking the surrounding landscape. Dating to the 11th century, the castle retains its original keep and defensive earthwork (vallum), which still bear witness to its role as a regional stronghold. The structure demonstrates exceptional medieval engineering and defensive architecture. Privately owned with limited public access, the château welcomes organized groups by appointment and opens to visitors during France's Heritage Days each September, offering an opportunity to explore medieval fortification techniques and learn about local history.
